1 Claim. (Cl. 42-68) William E. Donohue, Fort Worth, Tern, assignor of one 2,830,398 Patented Apr. 1.5, 1958 ends and are substantially closed at their rear ends except for axial orifices or firing tubes which communicates with primer receiving recesses 16 for receiving metal cased high velocity primers 17, such as those used in high pressure-high velocity cartridges. Such primers 17 are readily available since the same are used by gun enthusiasts when refilling spent cartridge cases. The primer receiving recesses 16 are inwardly tapered at a slight angle, for example, an included angle of one-half of one degree /2 and whereby the primer 17 may be pressed in place by hand and frictionally secured in firing position.

After the primers 17 are in place, the cylinder is positioned upright and high pressure-high velocity powder 18 cleaning. On the other hand, cap and ball loads are inexpensive as compared with cartridges, and may be quickly loaded in the ends of the cylinder chambers without removing the cylinder from the frame. Many gun enthusiasts prefer to refill fired cases for use in pistols other than theball and cap type, but such refilling is tedious and time consuming.

The primary object of the present invention is to pro vide a cap and ball type pistol having revolving cylinder capable of firing modern high pressure powder of the Magnum type.

Another object of the invention is to provide a ball and cap pistol of the revolver type which may be quickly and conveniently loaded.

A further object of the invention is to provide a hand gun of the described class which is safe in its use, and one which will not be discharged accidentally by reason i of exposed primers.

der and showing a charge and missile in the upper cham ber. Figure 4 is a front end view of the present cylinder. Figure 5 is an enlarged broken longitudinal section of the cylinder and showing the inner end of an ejector pin on an ejector rod positioned for ejecting the primer.

Figure 6 is a perspective view on a reduced scale of the ejector rod and pin.

The pistol shown in Figure 1 is generally of conventional design with the exception of the cylinder 10 and ejector rod 11, hereinafter described in detail. It is to be understood that the cylinder 10 is interchangeable with a conventional cylinder of the same overall dimensions for firing cartridges, and that the central opening 12 and ratchet teeth 13 are of the same dimensions for carrying out interchangeability. i

The cylinder 10 isrotatably mounted on a cylinder pin, not shown, and is provided with cylindrical chambers 14 therearoundg The chambers 14 are open in their forward is measured and poured in the open ends of the chambers 14. A missile 19 is then pressed in place and the pistol is thus loaded,'ready for firing. When a charge does not include a case, and in connection With pistols, such charges are referred to as ball and cap charges. It is to be understood that the missile 19 is preferably'of conven-, tional conical shape, but it is pointed out that spherical or other shaped missiles may be used. The primer 17 is introduced to its recess 16 by way of conventional loading gate 20, not herein described in detail.

The ejector rod 11 is also of conventional design and operation, except that the innermost end 20 is of reduced diameter and of suflicient length to pass through'the orifice or firing tube 15 for ejecting the firing primer 17. It is to be understood that the conventional operation of the ejector rod referred to ordinarily has to do with ejecting empty cartridge cases.

From the foregoing it will be apparent that the pres ent invention is capable of readily and conveniently receiving a modern primer capable of detonating high pressure-high velocity charge, thus providing a ball and cap construction for convenient hand loading and for greater trajectory and accuracy.

The invention is not limited to the exemplary construction herein shown and described, but may be made in various ways Within the scope of the appended claim.

What is claimed is:

In a'revolving firearm, a chamber cylinder comprising a cylindrical body mounted for rotation about the axial center'thereof, cylindrical recessed chambers in one end of said body parallel with saidbody axis, each said chamber being adapted to receive a powder charge and missile through its open end, inwardly tapered primer cap receiving recesses in said body and in the end thereof opposite the end including said chambers, each said primer cap receiving recess being in axial alignment with and spaced from a said cylindrical chamber, said cylindrical body having axial orifices respectively connecting said chambers with said recesses, the diameter of each said orifice being less than its connecting primer cap receiving recess, and a longitudinally reciprocating ejector rod slidably carried by said firearm and positioned to enter a said cylindrical chamber in axial alignment therewith, said ejector rod being of reduced diameter at its inner end, said reduced diameter being of sufficient length to extend from the inner end of the chamber entered, through the aligned orifice and into the aligned recess a distance suflicient to dislodge a fired primer cap therein.
